This study investigates the role of Islamic solidarity in the conceptions, motivations, and practices of Turkish HNGOs. While Islamic solidarity plays an important role in the conceptions, motivations and practices of these HNGOs, it is, at times, limited by their strong sense of affiliation with Turkey and Turkish patriotism. In this sense, Islamic solidarity can be downplayed when there is a stronger sense of national affiliation. Furthermore, the sustainability of these HNGOs, and therefore the extent to which they are able to extend Islamic solidarity, is dependent upon the convergence of their ideas and interests with Turkey’s current government. In a similar vein, it remains under question whether these HNGOs would feel the same level of patriotism under a different government. As such, the support they enjoy from the government and the affiliation they feel with Turkey feed into one another. Moreover, Islamic solidarity offered by Turkish HNGOs could be challenged by their overreliance on the precarious space provided for them by the current Turkish government.
